To all whom it may concern:

Be it known that we, FRED 0. Born and CHARLES F. LITTLEJOHN; citizens ofthe United States, residing at New Haven, in the county of New even andState of Connecticut, have invented a new and useful Improvement inHydrocarbon-Burners; and we do hereby declare the following, when takenin connection with the accompanying drawings and the characters ofreferencemarked thereon, to be a full,

clear, and exact description of the same, and which said drawingsconstitute part of this application, and represent, in-

Figure 1 a top or 'plan view of a hydrocarbon burner constructed inaccordance with our invention.

This invention relates to an improvement in hydrocarbon burnersparticularly adapted for use in burning kerosene oil, the object of theinvention being to provide a burner which may be inserted into theordinary fire-box of a cook stove or range, heating stove, furnace orother device in which coal or wood is commonly used; and the inventionconsists in the construction hereinafter described and particularlyrecited in the claims.

In carrying out our invention we employ a base-plate 6 preferably ofcast metal and corresponding in dimensions to the number of burnersused. our invention we have shown a device comprising two burners.- Thisbase-plate is supported upon an open rectangular casing 7 provided atits lower edge with an outwardly projecting flange 8 adapted to restupon the grate in the usual fire-box and so as to support the base-plateabove the grate and provide a passage for air drawn upward through thegrate. The base-plate is formed around its edge with an upwardly.

projecting flange 9 and with burner openings 10, the openings beingsurrounded by collars 11. The base-plate is also. formed with tubularopenings 12 through which feed pipes 13 extend, these pipes leadingSpecification of Letters Patent.

through the ordinary dampers 14in the front of the stove to a tank 15.Resting on the base around the edge of the collars 11 is a housing 16forming a mixing chamber above and aroundthe collars. These housings-areformed at their lower edge with lugs 17 by which the'housing may besecured to the base-plate 6. by screws 18. The lower edges of thesehousings are formed with notches 19 'to permit air to be drawn into themixing chamber. These housings are formed attheir upper ends Patentednet. flit, ilht o Application filed October 22, 1918. Serial No.259,223. i

with chimneys 20 smaller in diameter than the diameter of the housing soas to form annular priming channels 21 for the purpose as willhereinafter appear. The feedpipe 13 extends upward over the mixingchamber and is formed with a coil which extends down through the mixingchamber and terminates in an upwardly extending burner tube 22 providedat its upper end with a burner nipple 23. Over the coil in each mixingchamber is a distribu-ter 24 which is suspended on an arm 25 mounted ina post 26 which is secured to the baseplate 6 between the burners. Thedevice is placed in the firebox of an ordinary cook stove as indicatedin Fig. 5 of the drawings upon the grate-bars therein, or it may beplaced in any furnace or other fire-box where required. Upon the flange8 may be placed any packing, such as ashes, so as to cut off any upwarddraft through the grate which will all be deflected upward through thecasing 7. The pipe from the fuel supply is then opened to permit thefuel to flow to the burner and one or more of the burners may be used asis required. The heat from the burner vaporizes the fluid in the feedtube as it passes to the burner tip so that it emerges in the form ofgas, and this gas is spread by the deflector so as to cover the heatingsurface of a range or furnace. In first starting the burner, it may bedesirable to place some kerosene or other burning fluid in the primingchannel 21 so as to heat the burning fluid as it first comes to theburner tip. This in- -wardly set priming channel also restricts ings 19so as. to further amist in combustion and preferably, and as shown, theupper inner of the chimney or 21th cup will be formed with notches 2through which flames will 'be directed to the upper part of the coil. Itwill thus be seen that a burner for liquid fuel, such as kerosene, "is;provided, which is readily adapted to be placed in an fire-box withoutrequiring any change in the structure of the apparatus into which it isplaced.

We claim 2- 1. A hydrocarbon burner comprising a plate formed with anopening, a mixing chamber around said opening, said mixing chamberformed at its upper end with a priming cup, a feed pipe extending oversaid chamber and downward through the chamber inthe coil, said pipeterminating in a centrally arranged burner tip.

2. A hydro-carbon burner comprising a plate formed with an opening, anupwardly projecting collar around said opening, a mixing chamber casingmounted on the plate around said collar, said mixing chamer casingformed in its lower edge with notches and at its upper end with apriming cup, a coil within said mixing chamiaeae a ber 1 to the sourceof supply, and a burnerconn with the lower end of 3. A hydro-carbonburner comp baselate formed. with an opening, an upward y projectingcollar around said opening, an opencasing u on which the said base issupported, sai base also formed around its outer edge with an upwardlyprojecting flange, a mixing chamber caeing secured to said base aroundsaid collar, said mixing chamber casing formfi in its lower edge withnotches, and at its upper edge with an inset annular priming cup, a.
